Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for mounting a terminal with an electric wire on a connector housing and a terminal transfer structure at that time.

[0002]

2. Description of the Related Art A wire connection to a connector terminal in a wire harness or the like mainly employs pressure contact and crimping. The former pressure connection (hereinafter simply referred to as pressure connection) is shown in FIG.
As shown in FIG. 7, the cavity s of the connector housing C
And press-fitting terminal t is loaded on the housing C. First, the press-fitting blade guide 1 is placed along the housing C (FIG. 7A), and then the electric wire a
(FIG. 3 (b)), and the wire a is press-fitted into the terminal t with the press contact blade 2 and connected (FIG. 3 (c)). That is, the press-fitting press-fits the electric wire a into the connector housing C from above.

The latter crimp connection (hereinafter simply referred to as crimp)
After stripping the end of the electric wire (after stripping), the connection piece of the terminal is crimped on the exposed conductor to connect. For this reason, in general, terminals are crimped for each electric wire, and as shown in FIG. 29, chucking (pickup) is performed one by one with the hand 3 from the rear surface (terminal insertion port) to the cavity s of the connector C as shown in FIG. (See Japanese Patent Application Laid-Open No. 9-11564)
No. 2).

[0004]

In the above pressure welding, for example, in a conventional connector C having a two-stage cavity s in a wire harness, the wire is press-fitted from the upper surface of the housing C as shown in FIG. dividing the housing C in the upper C ₁ and a lower C _2, the upper housing C ₁ and after each loading terminal t and the electric wire a to the lower housing C ₂ (from FIG. (a) (b)), the cover b covered by, the two C _1, C ₂ are manufactured in one piece (FIG. (c)) (JP-a-10-335
037).

[0005] This conventional pressure welding operation is performed by a housing C ₁ ,
The C ₂ on top is two need, many working process, is causing the cost up. Further, the pressing force at the time of press contact wall e between the cavity s may bulge housing bends outward, or not Hisara cover b is well, there is a case where the lower housing C ₂ and the upper housing C ₁ is not well fitted . Further, due to the problem of the bending of the cavity wall e, in this type of press-connecting connector C, the terminals t are mounted on all the cavities s to eliminate the empty cavities s. That is, the terminal t is mounted in the cavity s which does not press the electric wire a, which is wasteful. Further, in order to newly press the electric wire a to the empty cavity s, it is necessary to disassemble the two housings C ₁ and C ₂ , and in practice, the press contact is impossible.

On the other hand, in the crimping connection, as described above, even in the connector C of the two-cavity type, one terminal (t) with an electric wire is inserted into the cavity s from the rear surface one by one and loaded. Connector housing C (not shown). However, it is necessary to connect the electric wire to the terminal t one by one, and there is a problem in workability,
Each one is easy to make a chucking mistake, and the wire a
Since the wire a is easily buckled as shown by the chain line in FIG. 29, the buckling causes mounting errors.

According to the present invention, under the above circumstances, even in a case where an electric wire is pressed against a terminal, the terminal with the electric wire can be inserted into the cavity of the connector housing from a rear surface thereof and can be loaded. It is an object of the present invention to be able to perform the insertion in both terminals at once.

[0008]

In order to solve the above-mentioned problems, according to the present invention, first, a terminal is mounted on a jig, and an electric wire is pressed or crimped to the terminal. In this manner, in the press-contact, as in the conventional case, the electric wire can be loaded from above the jig, and there is no problem, and a press-contact terminal with the electric wire by the press-contact can be obtained. In crimping, a crimp terminal with an electric wire can be obtained by mounting a crimp terminal on a jig and then crimping the peeled wire onto the terminal.

Next, the terminal with an electric wire is removed from the jig and transferred to an insertion jig, and the terminal is pushed out from the insertion jig and loaded into the connector housing.
In this way, similarly to the crimp terminal of FIG. 26, the terminals can be inserted into the cavity s of the connector housing C from the rear surface, and the terminals can be inserted at a time, so that workability is good.

At the time of transfer of the terminal, if the end face of the terminal from which the electric wire is led is fitted and supported at the tip of a member for pushing out the terminal from the insertion jig, the fitting support moves rearward due to gravity of the electric wire. The terminal is transferred into the insertion jig without tilting against the pulling force of the terminal.

The structure for transferring the terminal from the terminal holding jig to the insertion jig when mounting the terminal with an electric wire on the connector housing includes the holding jig, the insertion jig, and the insertion jig. And a jig for pushing out the terminal to
In the holding jig, a cavity in which the terminal is loaded is provided in parallel on an upper surface, a terminal to which an electric wire is connected can be pulled out from the cavity, and a lower surface of the pushing jig is provided on the lower surface. A through hole through which a pin passes is provided to the cavity, and the insertion jig can be brought into contact with and separated from an upper surface of the holding jig, and a cavity corresponding to the cavity of the holding jig is provided on the lower surface. A configuration that is formed to be open on the surface can be adopted.

In this configuration, with the insertion jig superimposed on the holding jig, the lower surface of the terminal is pushed up by the pins of the pushing jig to transfer the terminal to the cavity of the insertion jig.

At this time, it is preferable to provide a shutter between the holding jig and the insertion jig so as to be able to retreat, and to position the shutter on the lower surface of the insertion jig to prevent the terminal from dropping out of the cavity. If a guide is provided on the upper surface of the shutter when the terminal is pushed out of the cavity of the insertion jig, the terminal is smoothly pushed out of the insertion jig. Also, if the shutter is formed with a notch to avoid the push-up pin from the tip toward the inside, the shutter will support the front and back of the location pressed by the terminal pin, so that The support is stable, and the certainty of falling prevention is increased.

Further, if a transfer guide for terminals in contact with the upper surface of the holding jig is provided on both sides of each cavity of the insertion jig, the transfer can be performed smoothly. Without this guide,
When the terminal moves through the gap between the holding jig and the insertion jig, if a twisting force is generated in the wire (see FIG. 26), when the pin is pushed up (pulling up), the terminal is twisted by the twisting force of the wire. Rolling may result in delivery errors. For this reason, it is preferable that the holding jig and the insertion jig are brought into contact with each other and transferred. If there is a shutter, the transfer guide does not hinder the movement of the shutter.

The holding jig may be provided with the push-up pins. The push-up pins are provided in the respective through holes so as to protrude into the cavities. The jig base is provided on a slidable push-up plate, and the push-up plate is
What is raised and lowered by the lifting member from below the holding jig base may be employed.

In this way, when the shape of the cavity of the connector housing is changed and the holding jig is made to correspond to it, it can be dealt with only by replacing the holding jig.
That is, since the push-up member only needs to be able to perform the push-up action, it can be used also as the holding jig of each mode (see the embodiments of FIGS. 22 and 23).

At this time, if a spring that urges the push-up plate in the return direction in which the push-up pin withdraws from the cavity is provided on the holding jig base, the push-up plate returns by its own weight or the like, or the push-up member returns. And the like are not required, the operation is assured, and the cost can be reduced.

In addition, two through holes are provided in the longitudinal direction of the terminal corresponding to the terminals, and the push-up pins are provided in correspondence with the two through holes. , If both push-up pins are pushed up before and after the wire connection part of the terminal, for two-point support,
Since the pushing action is stable and the two points are located before and after the connecting portion, the load due to the weight of the electric wire is also stably supported, so that the pushing is more stable.

As shown in FIG. 8, on the jig 14, a spring plate 15 in which a strip-shaped spring piece 15b corresponds to each cavity 14a is screwed to the lower surface by a base 15c in which the spring piece 15b is integrated. When the plate 16 is screwed and the terminal t is inserted into the cavity 14a from the direction of the arrow, the plate 16 is positioned by the plate 16 and the projection 15a of the spring plate 15 bends like a chain line and is locked to the terminal t. To prevent the terminal t from coming off. The terminal t can be loaded from above. Terminal t is plate 1
It is preferable to apply the contact piece 17 to 6 to prevent its lifting. The abutment piece 17 is attached to the base 13 or another member, and retreats when a terminal t described later is pushed up (pushed up), and is normally urged downward by a spring while being pressed by the spring. The terminal t is swung upward to allow the terminal t to move upward. Two through holes 18 communicate with each cavity 14 a from the lower surface of the jig 14.

Various terminals t are selectively cut one by one from the terminal band from ₄ and mounted in the cavity 14 a of the jig 14.
At this time, mounting of the terminal t on the connector housing C is as follows.
Since the operation is performed in units of one jig 14, the terminals t are mounted on each jig 14 in the arrangement corresponding to the arrangement of the insertion terminals. Therefore, an empty cavity 14a may be provided in the middle. The terminal reels T _{1 to} T ₄ are appropriately moved as indicated by arrows, and correspond to the terminal band receiving positions of the terminal mounting machine 20.

The wire measuring machine 30 is disclosed in Japanese Patent Application Laid-Open No. 10-1544.
No. 23, Japanese Patent Application No. 10-349947, Japanese Patent Application No. 10
As disclosed in Japanese Patent Application No. 337042 and Japanese Patent Application No. 10-337249, an arbitrary electric wire a is selected from a plurality of supplies S, and a plurality of the electric wires a are measured at a time or one by one by a required length. It is sent out, and its end is gripped by the hand 31 and transferred to the next-stage pressure welding machine 40. The hand 31 is a measuring machine 30

The two arms are transferred alternately to the measuring machine 30 and the press-contacting machine 40 (see Japanese Patent Application No. 10-349947).

The pressure welding machine 40 is disclosed in Japanese Patent Laid-Open No. 10-241473.
JP, JP-A-10-106370, JP-A-10-106370
As disclosed in Japanese Unexamined Patent Application Publication No. 10-106371 and each of the above-mentioned unpublished applications, electric wires are selectively pressed one by one or a plurality of electric wires, and the end of the electric wire transferred by the hand 31 is fixed to a jig 14. To a required terminal t. At this time, the jig pallet 12 moves left and right, the terminal t at a required position is located at the press-contact position, and press-contact is performed. For this reason, as described in Japanese Patent Application Laid-Open No. 10-241473, various types of wiring can be pressed on the jig pallet 12. For example, as shown in FIG. 1 and FIG. 18, the jigs 14 are sequentially paired in the parallel direction, and wires are routed only to the pair, or as shown in FIG.
Various wiring modes such as mutually arbitrarily arranging electric wires can be employed. 19, an electric wire a as shown in FIG.
Becomes the crossed wire harness W. Therefore, electric wires are routed on each jig 14 according to the wiring mode of the wire harness W.

When the jig 14 is made of a hard metal such as steel, the wall between the cavities 14a is not bent by the pressing force. For this reason, if it is made of hard metal, even if an empty cavity that is not pressed against without inserting the terminal t is provided, there is no problem in terminal insertion in a later process. Further, the same pressure may be applied to the jig 14 as long as the shape of the cavity is the same regardless of the shape of the connector housing C. Incidentally, Japanese Patent Application Laid-Open No.
No. 106370 and other electric wire measuring machines 30 and pressure welding machines 4
It is also possible to perform wire scale pressure welding with a robot that has merged 0.

As described in Japanese Patent Application No. Hei 11-98716, the inspection machine 50 captures the state of the wire pressure contact with each terminal t using a CCD camera, and determines whether or not the pressure contact is appropriate based on the image. Yes, for example, it is determined by comparing a normal pressure contact state and a state that is not so. This determination may be made by a person or automatically.

As shown in FIG. 10, the terminal mounting machine 60
When the jig pallet 12 with the terminal to which the wire a is pressed is moved as shown by the arrow and comes to the terminal insertion position O, the terminal t is taken out from each jig 14 and the pallet 61 of the connector housing holding plate (pallet) 61 which moves to the left and right. The terminal t is mounted on the housing C, and details thereof are shown in FIGS. That is, an air cylinder 82 is provided in the base 10 below the terminal insertion position O to raise and lower the terminal push-up jig 81,
Above, a hand 70 having a terminal receiving jig (insertion jig) 71 is provided so as to be vertically movable. The receiving jig 71 and the pushing-up jig 81 have the number of terminals t that can be held by one jig 14, the receiving groove 72, and the pin 83, corresponding to the one jig 14 on the pallet 12. . The receiving groove 72 is a groove 72 into which a blade 73 described later is inserted continuously upward.
a is formed (see FIG. 11). A shutter 84 provided on the hand 70 is provided on the lower surface of the jig 71 on the hand side.
The pin 83 passes through a hole (notch) 84 a of the shutter 84.

Therefore, as shown in FIG.
When the push-up jig 81 rises with respect to the jig 14 at the insertion position, each pin 83 pushes up the terminal t in the cavity 14 a through the through hole 18 of the jig 14, and FIGS.
Is transferred (transferred) to the receiving jig 71 side as shown in FIG. At this time, the pin 83 comes into contact with the pressure contact portion of the terminal t before and after (points pq in FIG. 14) and pushes up. Also, FIG.
As shown in FIG. 13, a selected blade 73 described later advances in advance with respect to another blade 73, and a part of the terminal t fits into the tip 73 b of the blade 73, and the wire a is led out. The end face of the terminal t
Supported by For this reason, even though the wire a is pulled backward by the gravity of the wire a, the terminal t is not tilted and the jig 7 is not tilted.
1 (delivered). Since this delivery is performed in the cavities 14a and 72 between the jigs 14 and 71, pickup mistakes (delivery mistakes) are drastically reduced, and terminal insertion mistakes in later processes are also drastically reduced. Push up is two pins 83
Thus, it is preferable to perform the measurement at two points p and q, but the number may be one or three or more. In each case, the terminal t
Is raised without tilting.

The hand 70 is mounted on the base 10 as shown in FIG.
An upper frame 91 of the upper slide cylinder 90 is supported so as to be able to move up and down via a support plate 78 and a slider 79, and the frame 91 is moved by the slide cylinder 90 as indicated by an arrow, so that the frame 91 moves back and forth between a standby position and a mounting position. I do. The support plate 78 is moved up and down by an actuator 92 provided on the frame 91, and moves up and down at three positions, that is, the highest standby position, the lowest receiving position, and the middle mounting position.

The terminal receiving jig 71 is provided on the lower surface of the distal end of the hand 70, and the shutter 84 is provided on its side. The shutter 84 moves forward and backward by a cylinder 85, and when the delivery of the terminal t from the jig 14 to the receiving jig 71 is completed, the shutter 84 is sent to the lower surface of the jig 71 by the cylinder 85, and the hand 70
Is raised, the shutter 84 is applied to the front and rear of the lower surface of the terminal t to prevent the terminal t from falling out of the jig cavity 72. The jig 1 is used to feed the shutter 84.
Therefore, a gap is required between the
May be formed at the time of the above-mentioned lowering.
After pushing up the terminal of FIG.
Only the gap may be raised to form the gap.
Incidentally, if the jigs 14 and 71 are closer to each other, preferably if they are in contact with each other, the delivery becomes more reliable.

As shown in FIGS. 6 and 13, a required number (five in this embodiment) of insertion blades 73 are arranged in parallel with the insertion hand 70, and each blade 73 is provided with an air cylinder 74. Have been. By selectively driving the air cylinder 74, an arbitrary insertion blade 73 is protruded by a required length (symbol r) as compared with the other, and in this state, the lock pin 75 is pushed out by the air cylinder 76, and each blade is pushed out. 73 through the hole 73a. In that state,
After the hand 70 approaches the connector housing C and the air cylinder 77 advances all the blades 73, as shown in FIG. 13B, only the selected blade 73 pushes the terminal t to cause the cavity s of the connector housing C to move.
Insert 5 and 6, reference numeral 74a denotes a coil spring for returning the blade 73.

At this time, as shown in FIGS. 4 and 5, the member 87 having the terminal receiving jig 71 and the rod 87 of the cylinder 77 are connected to the rail 70 of the hand base.
a is slidably provided in the front-rear direction via sliders 86a, 87a, and is connected by an expand shaft 88. The expand shaft 88 has one end of the shaft 88a supported by a protrusion of one member 86 so as to be able to advance and retreat, and the other end fixed to the protrusion of the other member 87. A spring 88b is fitted, and a retaining ring 88c is fixed in the middle of the shaft 88a. For this reason, the air cylinder 7
When the rod 77a of No. 7 advances, the two members 86 and 87 advance until one of the members 86 abuts on the adjusting screw 89. Thereafter, the other member 87 advances against the spring 88b, and the blade 73 is moved. The terminal t advances toward the receiving jig 71, and pushes out the terminal t and inserts it into the connector housing C.

As shown by a chain line in FIG. 11, a guide projection 84b is formed on the shutter 84, and when a terminal is inserted, the stabilizers t 'on both sides of the terminal t are connected to the guide projection 8b.
It is preferable to proceed while being guided so as to straddle 4b. That is, when the terminal is inserted, the shutter 84 may serve as a guide. In this case, the terminal t is inserted smoothly without lateral deflection.

The operation of selecting each blade 73 when inserting the terminal t into the connector housing C is described in
This is the same as the selective operation of each press contact blade described in Japanese Patent No. 106371. In this manner, when the terminal is inserted by pushing out the blade 73, as shown in FIG. 15, the hand 3 is not provided due to the pitch of the cavity s (FIG. 15B) of the insertion of the press contact terminal t in FIG. The terminal t can be mounted even in the connector housing C (FIG. 9A) having a small pitch. Further, when a plurality of terminals t are mounted at the same time, the tact time is remarkably reduced as compared with the case where the terminals are mounted by hand one by one as shown in FIG. By the way, one by one, there is a limit to the tact-up, and mounting errors due to chucking errors are also likely to occur. Further, depending on the selection mechanism of each blade 73, if the spacing between the cavities s is the same, a housing C having a different size or a housing C having a lock portion
And if the interval between the cavities s is an integral multiple, it can also correspond to that.

As shown in FIGS. 2 and 3, the connector housing holding plate 61 is supported by a guide 69 provided on the base 10 so as to be movable in the left-right direction.
One end is fixed to a moving element 64a of a slide actuator 64 provided in the above, and the actuator 64 moves left and right as indicated by a chain line in FIG. The moving positions are a total of six points: three points where the housing holding frame 62 described later corresponds to the terminal mounting position O and three points where the housing holding frame 62 retreats a required distance therefrom.

As shown in FIGS. 3 and 9, a housing holding frame 62 is rotatably provided on the connector housing holding plate 61. The holding frame 62 is
And a spring 6 that presses and supports the protrusion 65
After the retaining ring 66 of the protrusion 65 is pulled and the housing C is fitted to the holding frame 62, and the protrusion 65 (retaining ring 66) is released, the housing C is pushed by the spring 65a. It is surely supported. The pressing force is a retaining ring 66
Adjust according to the screw-in amount. The protrusion 65 is a regulator 66
a, the holding frame 62 is set at the mounting position, and the cavity s at one level of the housing C is the terminal insertion position.

As shown in FIGS. 2 and 16, a rotary cylinder 63 at an insertion position O is provided on the upper frame of the base 10 behind the connector housing holding plate 61, and an engaging element 63a of the rotary cylinder 63 is provided. 17A by fitting into the engagement hole 62a of the holding frame 62 and rotating.
(B), the connector housing C is turned upside down (inverted) by 180 degrees. This operation is performed for each holding frame 62 of the holding plate 61. At this time,
Rotation of the rotary cylinder 63 is performed as shown in FIG.
When 5 is fitted to the restrictor 66a, as described above, the fitting causes the cavity s of one stage to be in the insertion position, but when the cavity is inverted, the cavity s of the other stage of the housing C becomes The rotation position is regulated by the cylinder itself so as to be the insertion position.

Accordingly, the terminal t facing the connector housing C by the above-described hand 70 is inserted from the rear surface into the cavity s of the housing C at the insertion position O and mounted by the advance of the blade 73. When the terminal is inserted into one stage of one housing C, the holding plate 61 moves to the left or right by a required amount, and the insertion hand 70 shifts to the operation of receiving the next terminal with wire t. The retreat of the inserted housing C is to prevent the electric wire a from being entangled at the time of receiving. When the terminal reception is completed, the holding plate 61 moves so that the one housing C is at the insertion position, and then the housing C is turned over and the terminal t is inserted again. At this time, the insertion hand 70 rises in accordance with the movement of the holding plate 61, and is positioned so as not to hinder the reversing operation. As shown in FIGS. 18 (a), (b) and (c), these actions are carried out on the pallet 12
The terminal t of the jig 14a is inserted, and the terminal t of the same (b) is inserted into the jig (b). Thereafter, the pallet 12 is similarly inserted into the housings C and C of II and III. c, d, e, f
Terminal t is inserted. This insertion order is appropriately changed in consideration of the wiring specifications, the degree of entanglement, and the like.

When the terminals t with electric wires have been mounted on all the connector housings C, the holding plate 61 moves to the right end,
The connector housing C is removed from the holding frame 62 by a person or a robot, and a new housing C is mounted on the holding frame 62. On the other hand, the jig pallet 12 is transferred to the terminal mounting machine 20. FIG. 20 shows a flowchart of the above operation.

The reason why the terminals are inserted by inverting the connector housing C is to mount the terminals t arranged in the same direction on the jig pallet 12 so that the upper and lower terminals t face each other. Yes, there is no need to flip it for the same orientation. Incidentally, conventionally, the insertion of the terminal t whose back faces each other has been performed after one terminal t is inverted. The number of cavities s is not limited to two, but may be one.
It may be more than one step. In these cases, the movement of the insertion hand 70 such as lifting and lowering is made to correspond to the number of steps.

By the above-mentioned terminal mounting, for example, a wire harness w shown in FIG. 21 can be obtained, in which the terminal t is inserted from the rear surface of the cavity s, similarly to the wire harness w by the crimp terminal t. . For this reason,
If the crimp terminal t can be mounted on the crimp terminal connector housing C, the crimp terminal and the housing C can be shared. If there is an empty cavity s,
Not only the insulation displacement terminal but also a crimp terminal can be inserted (mounted) into the empty cavity s.

FIGS. 22 and 23 show another example of the holding jig 14. In this embodiment, a push-up pin (push-up pin) 83 is attached to the jig 14. FIG. That is, the recess 14b is formed in the lower part of the jig base 14 ', and the above-mentioned push-up plate (push-up jig) 81 with the pin 83 is attached to the recess 1b.
4b, the plate 81 is pushed up by an air cylinder 82 (FIG. 22 (b)), and the pin 83 is always withdrawn from the cavity 14a by a spring 81a (FIG. 22). (A)).

In this embodiment, as the piston rod 82 'of the air cylinder 82 rises, the push-up plate 81 and the pin 83 are pushed up as shown in FIG. 22B, and the terminal t is pushed out of the cavity 14a by the pin 83. (Pushed up) and delivered to the receiving jig 71. Thus, by attaching the pins 83 to the jig 14,
The cavity s of the connector housing C is shown in FIG.
(Cavity width from A to B (A
<B), it can be dealt with simply by exchanging the jig 14 corresponding to the housing C. That is, FIG.
In the embodiment, not only the jig 14 is replaced, but also the push-up plate (thrust-up jig) 8 with the pin 83 from the air cylinder 82.
1 must be removed and replaced, which requires a tool change mechanism.
It is a troublesome task.

24 and 25 show another example of the insertion jig (terminal receiving jig) 71. In this embodiment, a transfer guide 72b is provided on both sides of the cavity 72 on the lower surface of the jig 71. is there. As shown in FIG. 26, if there is a gap between the two jigs 14 and 71 for feeding the shutter 84 and the like, when the pin t pushes up the terminal t, a twisting force is generated in the electric wire a. Due to the torsional force, the terminal t may roll as indicated by an arrow and a delivery error may occur. However, if this guide 72b is provided, FIG.
As shown in (a) to (c), at the time of transfer, the terminal t is guided by the guide 72b and smoothly moves from the jig 14 to the cavity 72 of the jig 71 without rolling.

If the width of the cavity 14a of the jig 14, the width of the cavity of the insertion jig 71, and the width of the cavity s of the housing C are sequentially increased, the terminal t having a reduced lateral width can be used. It is inserted into the wide cavity one after another, and the insertion operation becomes smooth. If the holding jig 14 can be crimped, the same effect as the above-described press contact can be obtained also in the crimp terminal.
